RIBBON-LOOM.

SPECIFICATION forming part of Letters Patent No. 636,979, dated November 14, 1899. Application filed March 2, 1899. 4 Serial No. 707,505. (No model.)

To all whom it may concern:

Be it known that LALERED GAETNEE, a citizen of theUnited States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Ribbon-Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to ribbon-looms; and its object is to simplify the construction of said looms by doing away with the heavybatten and the lay-swords supporting the same and by providing a longitudinal reciprocating frame orrail on which the shuttle-blocks, the reeds, and the operating mechanism for the shuttles are mounted. By this arrangement the loom is greatly simplified and rendered more effective and can be operated at a higher speed.

The invention consists in the improved ribbonloom,its horizontally-reciprocating frame or rail carrying the shuttle-blocks, reeds, and the shuttle-operating mechanism.

It further consists in the means for guiding and reciprocating said frame or rail and in the combination and arrangement of the various parts, substantially as will be hereinafter more fully described, and iinally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a side elevation of a portion of a loom provided with my improvements, the loom-frame being shown in dotted lines, and only such parts of the loom are illustrated which are necessary for a clear understanding of the invention. Fig. 2 is an enlarged transverse sectionalview of the reciprocating frame and of the parts mounted thereon, also showing a portion of the guide-rod and of a certain operating-lever. Fig. 3 is an enlarged detail front elevation of a portion of said reciprocating rail or frame (shown in section) and of the shuttle-blocks and intermediate reed mounted thereon; Fig. 4, an enlarged top plan view of Fig. l, the loom-frame being shown in full lines with certain portions in section; and Fig. 5, a view similar to Fig.

2, illustrating a slight modification of the reciprocating frame or rail.

In said drawings, a representsthe loomframe, in which is journaled the main driving-shaft b and the take-up roller c in the usual and Well-known manner.

In suitable brackets d e, projecting from each of the end sections of the loom-frame 0;, is mounted a guide-rodf, at right angles to the main driving-shaft and secured in their respective brackets by means of set-screws g or in any desired manner.

It may be well to remark that in the drawings there are shown only two rods f, one on each end of the loom, yet a series of intermediate rods maybe arranged, if desired, for 7o the purpose of strengthening the construction and mechanism hereinafter described. Upon each rod is slidingly mounted a bushing h, arranged in a two-part sleeve l,down- Wardly projecting from and onepart thereof preferably being integral with the rail m, which latter is parallel with the main driving-shaft and is intended to take the place of the ordinary batten.

The rail illustrated in Figs. 1 to 4, inclu- 8o sive, consists of a flat piece of metal m', pro- 'vided at its longitudinal edges with downwardly-projecting strengthening-ribs 'm2 m3, as clearly illustratedin Figs. l and 2.

On the top portion of said metallic frame or rail `is secured a wooden top plate or raceway n by screws n or in any desired manner. On the beveled rear portion of said top plate or raceway are mounted at specified intervals the shuttle-blocks q, of the usual and well- 9o known construction, which are adjustably secured to said top plate n by means of the clamps r, whose bent-over portions r are provided with set-screws r3, that engage the top portions of said shuttle-blocks, and whose lower portions are hook-shaped, as at r2, and

in engagement with the rail or frame m and its strengthening-rib, respectively, all as clearly illustrated in Fig. 2.

The pinions p are operated in the usual roo manner by the rack-bar o, which in the present case is slidingly arranged in the top plate or raceway n, and the reeds s are mounted between the shuttle-blocks and upon said top plate or raceway in a manner common to ribbon-looms, the usual strips u and u' being provided for the purpose of partially sustaining the reeds and of bracing the various clamps r.

Adjacent to each sleeve t' are downwardlyprojecting lugs t', (preferably integral with the rail m,) which are penetrated by a pin or axle i2, on which is loosely mounted the bushing i3, arranged in the forward end of the pitman 4, the rear portion of which is connected with the main driving-shaft or crankshaft l) in the usual manner.

The operation is obvious from the foregoing. Then the main drivin g-shaft is rotating, the pitmen are being operated, and by their connection with the downwardly-projecting lugs of the rail or frame m they reciprocate the latter upon the guide-rods f, and the reeds accomplish the beating up of the weft in precisely the same manner as in a ribbonloom in which thebatten is being oscillated.

In Fig. 5 I have illustrated a modified form of a rail. Said rail is somewhat narrower than the rail m in Fig. 2 and is provided on 'its front edge with an upwardly-extending flange m4 and on its longitudinal rear edge with a downwardly-proj ectin g strengtheningrib m5. On the top of said rail is secured a narrow wooden block m0, in which is mounted the rack-bar for operating the pinion, and which furnishes a base or support for the shuttle-blocks, as clearly shown. It must be remarked that said wooden block m needs only to be slightly wider than the shuttleblock, as its sole functions are the supporting ot' said shuttle-blocks and the furnishing of a bearing for the reciprocating rack-bar.

I do not intend to limit myself to the precise construction shown and described, as various alterations can be made without changing the scope of my invention; but

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. In a looln, the combination of a metallic :rail adapted to be horizontally reciprocated, a wooden top plate secured upon the top of the same, and provided with a longitudinal groove, a rack-bar arranged in said groove, shuttle-blocks arranged upon said top plate and extending over said rack-bar, pinions journaled in said shuttle-blocks and engagbar, pinions journaled in said shuttle-blocks.

and engaging said rack-bar, and clamps for securing said shuttle-blocks upon the top plate, each clamp having its lower end hookshaped and engaging a rib of said rail and havingits upper end overhanging the top portion of. the corresponding shuttle-block and provided with a set-screw engaging the latter, substantially as described.

3. In a loom, the combination of a suitable rail or f rame, a rack-bar operatively arranged thereon, shuttle-blocks mounted on said rail or frame, shuttle-driving pinions carried by said rack-bar, and vertical clamps for securing said shuttle-blocks to said rail or frame, each clamp having its lower extremity extending under and adapted to engage the rail or frame and having its upper extremity projecting over and having operative engagement with the corresponding shuttle-block, substantially as described.

1. In a loom, the combination of a suitable rail or frame provided with a longitudinal downwardly-extending rib, a rack-bar op` eratively arranged thereon, shuttle-blocks mounted on said rail or frame, shuttle-driving pinions carried by said shuttle-blocks and engaging said rack bar, and vertical 'clamps for securing said shuttle-blocks to said rail or frame, each clamp having its lower extremity hook-shaped and engaging the rib of said rail or frame and having its y upper extremity overhanging the top portion of the corresponding shuttle-block and provided with a set-screw engaging the latter, substantially as described. v

In testimony that I claim the foregoing I have hereunto set my hand this lth day of January, 1899.
